Michael Lewis’s books seem to get better and better. Whilst Liar’s Poker is often cited as a classic, I think The Big Short and now Flash Boys are more interesting. Flash Boys is particularly impressive given that the topic of high-frequency trading is under so much scrutiny, yet Lewis brings to light some of the practices going on in the industry that are not widely known. On top of that, he has a gift for making heroes out of otherwise unremarkable characters.
